    Abstract: A display device includes: a substrate including a pixel; a scan line for supplying a scan signal to the pixel; a data line for supplying a data signal to the pixel; a first power line for supplying a first driving power source to the pixel; a second power line for supplying a second driving power source to the pixel; and a third power line for supplying a ground voltage to the pixel. The pixel includes: first and second electrodes spaced apart from each other on the substrate; a plurality of light emitting elements, each of the light emitting elements having first and second end portions in a length direction thereof and being arranged between the first electrode and the second electrode; and a first switch electrically connected between the third power line and the first electrode. The first switch is configured to be turned on by a control signal.

    Abstract: A display device includes: a first substrate including a display area and a non-display area bordering at least a portion of the display area; a first transistor disposed in the display area, and includes a semiconductor layer, a gate electrode, a source electrode, and a drain electrode. A driving circuit is disposed in the non-display area, and includes a second transistor including a semiconductor layer, a gate electrode, a source electrode, and a drain electrode. An insulating layer disposed between the source and drain electrodes of the second transistor and the source and drain electrodes of the first transistor over the second transistor; a signal transmission line disposed in the non-display area, and transmitting a signal to the driving circuit; a second substrate facing the first substrate; and a sealant disposed in the non-display area between the first substrate and the second substrate, and overlapping the second transistor. The structure of the display device provides a bezel with a reduced width and resistance to pixel damage during formation of the sealant.
